Mat Griffiths

Hi my name is Mat and I live in Pontypridd I currently own a Lexus is200 and nearly 3 weeks ago a nasty lady ran into the back of my beloved car, and wrote it off, but I took the car to my local mechanic who said it's not too much damage if I can find a rear slam panel he could weld it in. However i have looked and searched and can't find one, do they even make such parts. If poss could you please direct me to somewhere where I could possibly resurrect my pride and joy
