I have an 04 V40 with 70K miles and have had exactly 1 mechanical (one of the tumblers on the ignition lock failed).
The V40 was a Mitsubishi joint venture and that car feels more Japanese than the V50.
The V50 is bigger, heavier, roomier, safer, more powerful and gets about the same mpg's.
Both cars have an elegant simplicity to them.
The V50 is understated and easy to live with.
If I drive slow I average 25 mpg with a mix of highway and around town.
If you need power its there.
The 5 cylinder turbo has been in production for years and should be reliable.
5 years 60K mile bumper to bumper warranty and free maintenance is unmatched. Like all Volvo's = many safety features.
utility, engine (the 5 cylinder turbo is unique), safety, warranty.
wider front seats, keyless ignition standard, standard transmission option, how about a diesel?
