What our customers say

"Very friendly service and extremely helpful staff. They took the time to ensure I choose the right car and I found the experience very enjoyable. The aftersales was first rate. Highly recommended."

Lee Carlisle

"Recommended to this place even tho I live in East London. Wanted an Octavia in good nick & they found me the perfect one within about 10 days!! Incredible low mileage & nick for the price - even had petrol in tank too!! Thx Myles & Rob for great service & friendly welcome & importantly good strong cuppa! It was certainly worth the journey cos they’re not like garages round here, it’s like you’re part of their family - you can really trust them"


"Key wouldn't connect and as it set off alarm. I rang MJ Warner and they came straight out to help me. No charge involved and as I had my grandchildren with me it was a difficult situation to be in. Many thanks to them for being so kind, helpful and efficient"
