Id like to see mook get into another GTP. Sounds as if hes just not interested in the Z anymore. Honestly the GTP is a great value for what it is. They are "cheap", reliable, and can be "fast" for relatively small money. Sure a LS1 is also relatively cheap, can be fast for small money, but its just not practical for everyone, and winter driving isnt the best. I cant really think of another car that can compare (for the money) at least.
That Daytona is a very nice car. It is kinda pricey, but it has low miles, its clean as fuck, and I (think) its built correctly. Id would seriously look into that if I was in the marker for another GTP and that was in my budget.
