Background
The Nissan President ran from 1965 to 2010 across four generations — H150 (1965–1973), H250 (1973–1990), HG50/JG50/PG50 (1990–2002), and PGF50 (2003–2010) — and sold almost exclusively in Japan as Nissan's domestic flagship against the Toyota Century. From the H250 onward the car carried a V8: Y44E 4.4-litre, then VH45DE 4.5-litre on the HG50/JG50, then VK45DE 4.5-litre on the PGF50. Most import buyers target the HG50/JG50 (1990–2002) for the VH45DE and its Q45 parts crossover; PGF50 cars become 25-year eligible from 2028 onward. The President was never exported under its own name — the closest equivalent is the Infiniti Q45, which shares the VH45DE and G50 platform but is a different body.
The VH45DE 4.5L DOHC 32-valve V8 debuted in 1989 in the Infiniti Q45 and arrived in 1990 in the third-generation HG50 President — Nissan's first DOHC V8, designed as a direct response to Toyota's 1UZ-FE in the LS 400. Output on the JDM President is commonly cited around 270 hp and 290 lb-ft, routed through a 4-speed automatic and rear-wheel drive.
The bottom end and timing chain are durable on regular servicing, and VH45DE parts cross-source from the more common Q45 in North America when President-specific items become difficult. The 2003 PGF50 switched to the VK45DE — a related but newer DOHC V8 also used in the Cima Y50 and the Infiniti M45 — quieter and lighter than earlier VK applications.
The PGF50 shares body panels, lights, and the F50 platform with the contemporary Cima Y50. Autech, Nissan's customisation arm, produced low-volume Royal Limousine builds throughout the HG50 era for fleet and ceremonial use.
The President's position in Japan derived less from performance and more from where it was parked: in 1970, two H150 units entered Prime Minister Eisaku Sato's official fleet, and the model carried government-use associations through subsequent generations. Nissan's pitch was always against Toyota's Century — the Century was the Imperial Household choice, the President was the corporate and government-official alternative.
The H250 Sovereign VIP trims added features that signalled ceremonial role over driving: rear-seat ABS in 1971 (the first ABS-equipped car sold in Japan), rear-seat air conditioning, and by the 1985 Sovereign VIP a signal phone and rear-seat television. The HG50 era introduced the Royal Limousine built by Autech — proposed as a replacement for the Nissan Prince Royal used by the Imperial Household, not accepted, but producing one of the rarest President variants.
The 2010 cancellation reflected the same demand collapse that ended the Cima: tightening safety regulations, declining corporate-sedan demand, and the Fuga absorbing the flagship slot.

Chassis history
The President ran from 1965 until 2010 across four generations, and each one was a different car for a different decade. The H150 and H252 are old-school chauffeur sedans with the early V8s. The HG50 is where the modern VH45DE V8 arrives and where most import buyers start. The PGF50 is basically a top-trim Cima Y50 with a President badge.
Third generation — JHG50 / JG50 (1990–2002)
Buyer's call
The President trades a lot to be what it is. You get a Japan-only flagship V8 with chauffeur DNA and almost nobody else has one. You also get parts hunts, niche electronics, and a small buyer pool when you go to sell. The good and the bad on the President come from the same place, which is rarity.
Reliability
The VH45DE under the HG50 is a tough engine and the chassis is overbuilt. Most of what goes wrong on a President is age related. The cooling system tires out. The air suspension on equipped cars starts to sag. The interior electronics and climate control modules drift. None of these kill the car, but they all cost money to put right.

Market
The Nissan President was never officially sold in the United States, Canada, or any export market under the President name across all four generations (1965–2010). The closest export equivalent is the Infiniti Q45 (G50, 1989–1996) and (FY33, 1997–2001), which shares the VH45DE 4.5L DOHC V8 and core G50 platform with the third-generation HG50 / JG50 President but is a distinct body and interior — the President sits on a longer wheelbase, carries different exterior styling, and uses a ceremonial-spec rear cabin that the Q45 never offered. For US buyers, the only path to ownership is the 25-year FMVSS / EPA import exemption: H150 cars (1965–1973) are long-eligible, H250 cars (1973–1990) eligible by build date, and HG50 / JG50 / PG50 cars (1990–2002) eligible by build date now. The PGF50 (2003–2010) is not yet eligible — the earliest 2003 builds become importable in 2028. The driving position is RHD across every President generation; there is no LHD President, and there was no factory left-hand-drive program for any market.
Specs
Every President from the H252 onward runs a V8. The early Y40 and Y44E V8s are old-school iron with simple electronics. The HG50 brings the VH45DE 4.5 liter, which is Nissan's first DOHC V8 and the same engine that sits in the Infiniti Q45. The PGF50 swapped to the VK45DE 4.5 liter, which is smoother but more complex to service.

Lineup
President trims line up by how much of the rear cabin is set up for someone other than you. The base President is the driver's car of the range. The Sovereign adds leather and wood. The Sovereign VIP is the chauffeur trim with rear comfort features. The PG50 Royal Limousine is a factory stretch built by Autech in small numbers and the rarest of the lot.

Pricing
Rough imports of the President can be cheap because the buyer pool is small. Clean documented cars are a different story. Expect a wide spread depending on condition. A driver-grade HG50 sits in the lower end of the range. Low mileage Sovereign VIP cars with records are at the top, and the PG50 Royal Limousine is its own market.
Today's market range: $8,000 to $45,000 (median ~$22,000). Source: JDMBUYSELL / USS Auction.
Market is niche but firming: clean G50s are appreciating as VIP/JDM luxury grows. Prices are condition-led with big spreads; top-grade, low-mile, unmodified cars see the strongest bids. PGF50 interest is building ahead of 2028 legality.
Inspect
The President checklist is heavier on documentation and rust than on the engine. The V8 itself is usually fine. What you're really checking is whether someone has kept up with the cooling system, the suspension bushings, and the interior electronics over the last 25 to 30 years. Bring a flashlight and crawl under the car.
Cross-shop
If the President turns out to be too much of a parts hunt, the natural alternatives are the Toyota Celsior for a smoother V8 with proper parts support, or the Nissan Cima Y33 if you want the President feel with an easier ownership path. The Infiniti Q45 G50 is the closest mechanical cousin and gives you US parts access on the VH45DE.

Among the JDM flagship sedans, the President is the rarest, the Celsior is the most reliable, and the Toyota Century sits above all of them with the Imperial Household association and a V12.

Editorial
The safest starting point is a documented HG50 or JG50 from the 1995–2001 range. That gives you the VH45DE 4.5-litre V8 with a long service history available through the Infiniti Q45 parts ecosystem, and electronics old enough to be sorted without being so old that every module has given up. Avoid cheap examples without records — a bargain President typically becomes a parts hunt, and what you save at purchase you'll spend chasing trim and rear-cabin hardware that nobody outside Japan stocks.
For the Sovereign VIP rear cabin and long wheelbase, confirm you have a Japan-direct supplier before committing. The PG50 Royal Limousine sits above that — the drivetrain is the same VH45DE, so the engine isn't the concern. Plan partition glass, rear lounge controls, and chauffeur hardware at an extra three to five thousand over the first few years.
The H150 and H252 without service history are the cars to pass on. The early V8s and older electronics are harder to sort than the HG50, and H250 parts get scarce quickly. A clean H252 Sovereign with original interior and documented cooling work is worth a closer look, but most rough H250s cost more than buyers expect once the work adds up.
The PGF50 is not yet 25-year eligible in the US — the earliest 2003 builds qualify from 2028 onward. Where it is importable, treat it as a top-trim Cima Y50: same VK45DE 4.5-litre V8, same F50 platform, and service items that mostly cross-reference to the more common Cima.
