Thanks @baburwawan, @majid and all for the appreciation. Here is the latest update...
Spent my whole yesterday on my liana. First i took it to a 3S master motors on queens road, got my car completely checked up from there replaced spark plugs, oil, filters, Fan and AC belts, got the tappet work done (Shims replacement), Serviced the breaks, the pads and drums were in good condition so no replacement was required.
Total expense was 10K +.
Then went to montgommery road and got the seat covers installed, not very satisfied with the fittings but OK. Bought a new Bosch Horn for my Liana sounds pretty good.
Total Expense 3,000/-
Then went to Hall road for the fitting of speakers amplifiers and sub, saved the original phatta and got a custom made installed for Rs. 600, got a small bass tube for the sub, since less space is left within the boot with previous bass tube, difference paid Rs 400, Fitting Cost Rs. 600/- for all.
Total Expense Rs. 1,600/-
My car runs very smooth now MashAllah....
very much satisfied.
