The version owners recommend
Insufficient owner data available to declare a consensus. The only partial signal is negative: early E65/E66 cars, especially the V8 and V12 models, are singled out as the worst, and one owner states the E66 is "mostly garbage" as a whole. No specific model year or trim within the generation is recommended.
Competitors to consider
Owners compare it most often with the Lexus LS430, Lexus LS460, Lexus GS350, Mercedes-Benz E-Class and Mercedes-Benz E550.

Overall sentiment
Owner sentiment for the 2001-2008 E66 7 Series is overwhelmingly negative, with the vast majority of discussion participants advising against purchase. The car is repeatedly described as unreliable, electronically complex, and extremely expensive to maintain relative to its low purchase price. Owners who defend the car do so conditionally, noting that it can be a rewarding drive and a genuine luxury experience only if it is already in near-perfect condition and the owner can perform their own work or afford a specialist. A recurring theme is that the low asking prices are a trap, since maintenance and repair costs reflect the car's original six-figure flagship status rather than its current value. Early cars, particularly the V8 and V12 models, draw the harshest criticism, while even later examples are described as a "hornets nest of problems."
Positioning vs competitors
Owners consistently position the E66 as the least sensible choice among its alternatives, recommending Lexus for reliability, Mercedes for a somewhat better ownership experience, and smaller BMWs such as the E46, E39, E90, and E60 for lower running costs and easier parts availability. The E66 is framed as offering superior luxury and driving experience when healthy, but at a cost of ownership that most buyers in its price bracket cannot sustain. Several owners note that a Lexus lacks the excitement of the 7 Series but will be far less of a headache, and that buyers drawn to the 7 Series are unlikely to be satisfied by a Lexus anyway.
Recommended configurations
Insufficient owner data available. No owner in these discussions recommends a specific engine, trim, or model year within the 2001-2008 E66 range. The only configuration-level guidance is avoidance: multiple owners warn against the V8 and V12 models, and one advises against any 7 Series from 2002 through 2008.
General recommendations
Owners direct almost all prospective buyers away from this generation. The only buyers given a conditional green light are experienced DIYers or those with a strong BMW background who can do their own work, have a large repair fund set aside, and buy an example that is already in near-perfect condition with full service history. Recommended alternatives within BMW are the E46, E39, E90, and E60. For inspection, owners advise having a skilled mechanic perform a thorough pre-purchase check and verifying that every service has been completed. One owner recommends changing oil twice as often as the service interval and changing transmission fluid every 30,000 miles.
Remarks
A recurring observation is that the E66 depreciated to a fraction of its original price precisely because of its running costs, and that many examples are sold just outside warranty because owners know what is coming. One owner notes that third-party parts are scarce for the 7 Series because so few were sold, forcing owners to buy from BMW at higher prices. Another describes the car as a love-hate relationship and a learning experience. Analysis based on approximately 26 substantive owner discussions about this generation.
