Depends on your car's total condition, Mileage, how long an MOT, Petrol / Diesel / Colour / Manual / Auto, do not use the company you Mention, they will ripyouoff.com
Company near me tells people to go to webuyanycar and get valuation, he will then pay 20% more. That kinda tells you how bad their offers are...
Also, (for fun only) I took my 2004 Renault Megane in and their offer was £165 and then they take an 'admin' fee. I sold the car through the local paper for £440.
