Thing of interest:
I let the registration lapse last month so the tags are not current any longer, I just dont drive the car at all anymore and didnt feel like dealing with the hassle. I will most likely register it non op in the next few weeks.
cost of maintenance is all relative.... if you are a DIY'er its cheap, a 10 dollar filter and 6 quarts of oil and your oil is changed. If you have to bring the car to me for maintenance then expect a 15k service to cost around 6-700 dollars... its an oil change, spark plug replacement, air and fuel filters get replaced and the timing and balance belts get adjusted.
can you change the fuel and air filters? spark plugs?
do you have the belt tension tool to do a proper belt adjustment?
I do still have the car though registration for me was about 76 dollars/year
