for your first question, yes you can find an eg in 5lacs (if Punjab regd) stock non swapped but you will need too hunt for good car, as now a days very few are up for sale and the ones who are for sale are already riced or accident-ed, and you may find khi regd lil more cheaper !
good quality paint job costs 50k almost and denting and all other charges are excluded ! regarding D-series you would be lucky if u find good one now a days, stage 1 costs up to you which type of parts like headers, intake, plugs etc you are using costing somewhere 30k !
