Dearest Umair bhai
buhat buhat buhat hee zeyada mubarik baad for new ride and sad to know
1) u sold ur civic
2) again silver ??:o
anyway color is something personal choice and may Allah prove this car safe and enjoyable ride for u and ur future wife 
Umair bhai car registration is not big science , why waste hard earning on bribes to agents ?? do it urself, just go there get payment slip from counter as per ur car engine capacity and remit amount in national bank in same building and back to first window, if u go early morning than it wont take more than half an hour, i always did it myself and its easy, instead of giving rs2k to agents better give that amount to real needy person in ur surrounding
recently visited lahore tyer market alongwith friend who wanted to replace his car's tyers , we wished yokohama but somehow shopkeeper convinced us for "Toyo" tyers " its made in japan and manufacturing date also ok , frankly it was good move , car's drive is smooth, soft and no noise , fully satisfy on our decision
about seat covers i would recommand u fabric body fit style , though i am in leather industry but personally i dont like leather seats
many options of good quality fabric and all depend upon ur pocket, roughly in rs 5k u will get reasonable set
floor mats , good quality carpet mats give elegance looks
steel mate working well in city without any issues upto now
and most important and my favorite subject how to care this beauty 
get urself one sealant bottle to protect ur silver beauty skin from very first day and than maintain with wash and wax 
Autofinesse tough coat sealnt spray is easiest product, wash and dry ur car and spray this sealant ( 2 spray on one panel enough and by help of soft clean foam applicator pad even out and once u do whole car give 1 hour hazing time and than buffout with soft cleam microfiber , 2 applications will give even and best protection )
