owned both
It might be crazy but I like the GTI more than the BMW 335i. My GTI has an ARP Tune and other tasty add ones. This car has it all. Overall packages the GTI is the best car out there. Owned E36M3, 2x BMW 335s, Honda Civic SI Mugen, and others. GTI is very reliable, I avg 32mpg, interior is perfect ( I have autobahn pcg.), excellent manual transmission, car looks super sleek. Forgot to mention that it's a great family car. Drove across the country with no complaints. Like someone already mentioned in the thread, there is a lot of options for power increase, to include new turbos to push over 400hp...good luck with that though.
