Not a specialist car

I have created car with an engine that i had kicking about and to my surprise, with some work and tossing lots of bling into it, I made it rate over 70 in 8 market sectors, and I made it rate 90.1 In family sport premium.

Would this car be a hit?

The depends on the volume of production and the size of the markets you are targeting. as it stands a generalised product that sells over a range of demographics would expect to perform decently well regardless.
