I had an octavia vrs for two years and loved it, had a blue flame cat back piper cross air filter baily dump valve and mine nevr threw up any fault codes. had to do a few minor repairs on it but i found the parts to be pretty cheap for it.
Good owners club is BRISKODA.NET good bunch of guys on there.
I now have a clio 172 and its a great wee car takes a hell of allot of abuse from me and keeps going, sure build quality isnt as good and there is a few rattles but they handle well and go alot better than a fiesta st.
