I would stay away from the vauxhall. Paint is crap, engines dont last long and on top of that they are plagued by electrical gremlins.

If you spend 10k on a FRS.... then it's going to be a low miler that you wont want to be driving every day.

The renaults are a nice spec plus being turbo you can get them running serious power fairly easily. Plus you wont worry so much when you park it in the supermarket! Plus I think it's quite a lot of car for the money / age etc.
I would look to spend no more than about 8k on one though.

if you decide on any of these cars I would buy it privately from an owners club member. Join a couple and see what you like the look of. All the best cars are found on the forums imo.
