My Mk4 was an import and its been a bit of nightmare - you only get a 1 year warranty, and you loose a grand in value ontop of what the book says.
Check out some of the brokers.
I got my 2.0 TDI 5door, with winter pack, pearl effect paint, luxury pack 2, arm rest, storage pack for just over ?17k new saving 2k (11% off), from www.uknewcars.com (they have arranged discounts with s elect dealers all over the country, I'm picking mine up from Northampton)
