Couple of Quickies, 2005hb ?s

[Willys]

Hi guys:
I just got my 2005 HB and was wondering whether or not anyone else tows with theirs and what do you tow with it? Also ,does anyone use synthetic oils, and when did you start using them? and what type or brand? Does it make any differance? Do you have to use them constantly once you have used it once or can you go back to ordinary oils again? What size are the front door speakers and how easy is it to get at them? I don't have any there as of yet but have some expensive speakers and an amp to put in if I can fit the speakers in the doors without ruining the door panels. This cold air intake tube? what is it and is it worth buying? I didn't ask the dealer ,my stupidity, but do the Echo's come with a frostplug heater,blockheater of any type? If not which one do you recomend? Inline ,hose type or frost plug design? Mine came with Michelins on it ,what sort of mileage am I to expect to get out of them? sensible driving, not any drifting by me lol!!! Seat covers? what type or design has anyone perfered to get? Has anyone tried the leather look ones from Canadian tire yet? They sort of look good and perhaps comfortable too? $29 each. last but not least...has anyone else used Rustcheck on their new car and what did you think of it and most important did it ruin your new car smell!!!????
I will be getting it done soon but was curious about the new car smell loss!! Man that smalls good after driving a piece of crap all thes years giving the last new cars to the wife!!!

Well those weren't exactly a few questions but I kept thinking,, sorry!!
Thanks
