My Cousins Mustang GT. Ford Racing S/C kit (intake, intercooled, blah blah), roush kit, full suspension upgrade. Made 457/491 on a mustang dyno. it went from completely stock to this in 2 weeks at the cost of about 18k.

Also My uncles daily driver. Audi S5, stock. Just sold his 2nd R8 and ordered a Rossian Q1.

Must be nice to have money to blow like that.
