ive always loved the mk2 gti - oak green and royal blues

always admiring from a far, im now wanting to chop in my clio 182 for something with some character, so a golf it will be!
ive always had new cars so should i be worries about buying with milage well over the 100k mark? in some cases on pistonheads 160k! are they still reliable and still pulling strong??? im aware that spares are plentiful.
i have real strong ideas on exactly what i like. sitting low on bbs rims, and ive seen on some cars the wing skirts painted instead of the black plastic, that looks nice!
it'll get a fresh coat of paint in an attempt to turn it into a real show car no doubt.
i have a million questions so ill search the forum to answer those!
thanks guys,
dave
