Best Porsche for ~£20k?

Hi all, I’m from the UK and have about £25k to spend on a new car/cars. I’m looking to get a £5k daily and £20k porsche. There are plenty of 987.1 CS about for that price but I’m worried about IMS/Bore Scoring problems.

As experienced Cayman owners, what would you recommend I get for circa £20,000?
