BMW 7 Series Buyer's Guide
The 7 Series depreciates harder than almost anything BMW builds, which is exactly why it appears here. Both of our sold results are E38s from 2000: a 750iL V12 at £10,125 and a 728i at £6,400. That is flagship-grade engineering, bought for less than the original cost of its option list, and the E38 is now firmly a modern classic rather than a cheap barge.
Know your generations
The E23 (1977–1986) started the line with the 728i, 732i, 735i and turbocharged 745i; survivors are rare in the UK. The E32 (1986–1994) added the 300bhp 5.0 V12 750i and 750iL, the car that restarted the German twelve-cylinder arms race. The E38 (1994–2001) is the one the market has settled on: handsome, understated, offered as the 728i, 735i, 740i (4.0 then 4.4 V8) and 750i with the 5.4 V12. Our two results both come from this generation, and the spread between them (£6,400 six versus £10,125 twelve) is about right for condition and cylinder count.
The E65 (2001–2008) brought Bangle styling and first-generation iDrive; brave value today, with the 6.0 V12 760i the wildest of the lot. The F01 (2008–2015) and G11 (2015–2022) are depreciating luxury cars rather than classics, though the 609bhp M760i will find its collectors. The G70 (2022 on) is current.
What to pay
Two sales: £10,125 for a 2000 750iL (May 2026) and £6,400 for a 2000 728i (August 2026), median £8,262. Active listings frame the wider market: a 1997 728i estimated at £2,500–3,500 shows where scruffier sixes start, and a 2005 E66 760i long-wheelbase carries a £7,000–9,000 estimate, which is remarkable for a 6.0 V12 limousine on any terms. A 1998 740i is running at no reserve. In short: £2,500–3,500 opens the door, our £6,400–10,125 results represent good usable E38s, and nothing in our data yet tests where a concours V12 or an E23 would land.
What goes wrong
E38: the M62 V8s (735i/740i) suffer timing-chain guide failure, a four-figure preventative job that is cheaper than the alternative; the Nikasil bore issue affected early cars but survivors have long since been sorted or replaced. V12 750s double every cooling, ignition and vacuum component and the bills with them. All E38s rust around the jacking points, sills and boot floor, and pixel failure in the instrument cluster is near-universal. E65/E66: iDrive and electronic gear-selector faults, air suspension compressors, and the 760's V12 requires specialist care; these cars are cheap because fixing them is not. F01: N63 V8s eat valve-stem seals and injectors. The plain sixes (728i, 730d) are consistently the most durable engines in every generation.
Our view
The E38 is the pick and the market agrees: it is the best-looking 7 Series, the last analogue one, and at our £6,400 result for a 728i it is absurd value for what it is. The six-cylinder cars are the ones to keep running as classics; parts are shared with lesser BMWs and nothing about them is exotic. The V12s are magnificent and ruinous in roughly equal measure; our £10,125 750iL buyer got a lot of car and a lot of future invoices. Buy an E38 728i or 740i with history now, while the whole generation still costs less than a mid-range hatchback.
