540 is on par with an E500... not as much prestige though! I'm a SAAB guy anyhow. Well I used to be before I sold both of them (one at a 50000 loss after only 5 years! stupid SAAB resale) to change my career and do the bike thing.
Life is much simpler and enjoyable with no car and associated payments! Combined, we make WAY less than you and easily support the three of us with money in the bank.
