Cars that look nice but are cheap?

I am beginning a new career where a nice(er) car can help better your image with people and get more deals done (Sucks, but it is what it is). Right now I have a 1994 Toyota Corolla which runs good but rattles and looks terrible haha.

Now, I am wanting to save as much money as possible, and I'm sure for the first few weeks I can use my parents vehicle when meeting clients, but I want to get my own asap.

So what are some cars that look nice, are good quality, and are relatively cheap? A new car is not needed, but I don't want one older than 4-5 years.
