Thanks a lot for the kind reply. You are an excellent helping hand on Pak wheels, sir
Yes, currently I own a silver colour car and literally speaking, I do wash it with shampoo and plain water and the results are satisfactory for me, as rightly pointed out by you 
Funds are no problem, but main problem is resale of 1.8 as I have experienced 1.8 owners complaining about its poor resale. As compared to 1.3 and 1.6, 1.8 doesn't enjoy good resale. Though, I can ignore the resale factor to some extent, but it has so far been the greatest impediment in going for 1.8 CVT.
Nevertheless, I wanted to ask you another thing: Why didn't you go for grande. If you were short of funds, you could have sold your Mehran and easily fetched enough to buy the grande rather than 1.6? Apologies if I am becoming too personal, but I have been thinking this question for a while? Thank you very much once again for your kind reply sir.
