If you have seen an R32 do what it does best, its impressive. They do need a bit of work to get the best out of them, but if you think that 1 second less in the 0-100 times is not much, why bother with the GTI at all? The 118TSI was Drives car of the year from memory as it had most of the toys and performance without the extra price tag... The VW spec says the 118TSI is 1.1 sec slower than the GTI, practically nothing?
When you start getting fairly fast, 1 sec faster in the 0-100 times is a lot. They do drink like a V8, but it can do things the GTI cant from a FWD perspective.
Don't get me wrong, I think the GTI looks to be a great car and all the reviews talk highly about the MkV to MkVI platform improvements, but the R32 is a great car too, I'd be very happy with one if i had the budget. with the MkVI being so popular, we may see the resale of the R32's dropping quickly and I might end up in one!
