read moreOutstanding service on my Mustang. Mark walked us through the process and explained all the options on which treatment and what the benefits were etc. Price quoted was price paid. DVD of before and after showed the limited coverage that had been applied by the factory, the after pictures couldn't be more different.

Family run, integrity, honesty and a down right fantastic job. Highly, highly recommended.

read moreExactly what I was looking for, meticulous attention to detail, fantastic job done in a few days.
Mark even had my tired alloys refurbed saving the hassle and time of me taking the car elsewhere.
I'm always dubious and over protective leaving my car with anyone but Mark and Sam put me at ease straight away.
I highly recommend Preserve and Protect and have already set a reminder to book in for my anniversary inspection!

I'm 'old school'; been into motors all my life and love perfection. Mark and Sam have a great understanding of what people like me need, and they most certainly 'tick' all the boxes. Very refreshing to deal with, will most certainly be returning with other vehicles and will highly recommend to all my friends and anyone else sensible enough to listen.
Finally, THANK YOU Mark and Sam for all your hard work. Very much appreciated.

read moreAfter searching online to find somewhere to underseal my MX5 as it was starting to rust a little. I came across preserve and protect, after a couple of friendly emails i popped over for them to have a look. Couldnt of had a more friendly welcome! With a up of coffee in my hand mark popped it up on the ramp and showed me underneath. He explained the process of the ubdersealing. Turns out they are a fan of the MX5's and gave me a ton of advise aswell as sourcing me a window regulator which i was looking for! Mark even managed to give me a run to the station to get home! All in all a great experiance
