I got Driver Parallel Lines for the Wii and I beat the game. But I cant find the Hot Rod, do you guys know where it is?

Have you collected all the gold stars?

no because I thought that unlocked free garage.

You have to win the GP Race in 2006, I think it is in Long Island.
But I did that in the PC version, don't know if it's the same in the Wii one.

I won all the GP races in 78 and 06 but I didnt find it
it was my enemy in the long island GP, tho

The xbox and ps2 versions either required you to enter in a cheat to get every vehicle but with the Wii you don't have that option because someone forgot to publicly release those cheats so you have to find the cars.
You cannot find the hotrod so you have to earn it, I know in the ps2,xbox version you have to collect 50stars and I think you have to do this in the Wii version.

I don't own the Wii version so I cannot give you a proper verifyed answer.
But this is close as I can give you.
