Banging a BAM 1.8t into your Caddy from an old Audi TT is all the rage. Its easy too as long as you can find someone to help with the electrical side of life, but chekc out this BAM 1.8T v5 in a VW cadyy which was modified to a high degree. The Caddy also has air ride so as to get down low low low low low low low.
