"slow" big engine car

[Mirinjawbro]

Hello

due to the temptation to plant the right foot too often ive decided i need to get rid of my car and have something that is "slow" so they'll be no temptation to speed.

am looking at big engine cars so at least i have the sound.

minimum 3.5 litre
budget 15k.
ideally coupe but saloon considered
as new as possible for that budget

thanks
