Welcome to GT6 and GTP 👍
Check out the garages here. I think for classic muscle cars you wont find one garage that has them all. @Bowtie-muscle runs a great garge for Chevy cars wont find many other american cars in it tho lots of JDM and Euro cars too.
Exter Tuning by @shaunm80 is great for a varity of cars has over 400 tunes in there.
