First car: Vauxhall Nova
Dream Car: Was my E55 I bought last year….Looking for a CL65 soon

If you cut Olly in half, we are pretty sure he would have a Star through his middle. A self-confessed car geek, Olly’s nose is always in a magazine or his phone looking at the latest technology and industry news. He passion for cars started when he was just 4 years old, tinkering with an old engine with his dad. Olly knew from a very young age that he either wanted to race cars, or fix them…and for a while he actually did both.

Jack Sykes
Born: 1987
First car: Vauxhall SR Nova
Dream Car: Zonda

Jack joined Olly at PCS in 2009 after working together at Mercedes-Benz Portsmouth. Jack was, and still is, a brilliant asset to the PCS family. Jack became a Dad in December 2018 so this is taking up a lot of Jack’s spare time at the moment but he still tries to find time to get out on the road on his Harley. Jack also loves a car project.

Her big love (other than Graham) is horses. Tacha has a house full of ribbons and rosettes so it was no surprise that her passion rubbed off on Graham. Their weekends are always spent together with their horses, whether at competitions, meets or simply mucking out.

Karen Reeve
First car: Red Vauxhall Chevette

Karen is Olly’s sister and for as long as she can remember, has always tried to stop Olly spending all of his money on cars. That’s why she is the perfect bookkeeper for PCS.
