Hi all, going to check out a mk4 gti 180 on Friday. Got an itch since my other half made me sell my mk4 r32 8 years ago after just 6 months of ownership. Decided to go for a gti and not an r for fuel economy reasons

Have plans to make some minor performance and aesthetic changes early on. Any advice on any obvious known issues to check out as well as easy initial modifications will be gratefully received.
Thanks all in advance
