I don’t have any car loans. FWTW. Just maintenance and repair expenses. Three cars, monthly average costs on each including purchase, maintenance, repairs and replacements of parts, state inspections, and excluding fuel and insurance in $165 or under, after allowing for current resale value to a private buyer. Those costs would be federal sales taxable? Some part at least.
I would think “parts”, since they are new would be taxable, but not labor but we don’t know if services are taxable yet. Boy you have some low auto repair costs, we have three cars too, My son’s 2005 Mustang we bought new, my wife’s POS 2003 Golf bought new and my 2000 Suburban also bought new. Every time they go in the shop it’s a minimum of $1000 but averages more like $2000, I’d say we spend a minimum of $5,000 a year on them which would average more like $400 a month. Add that with a ave. $1,500 a month mortgage, HVAC, water, misc, $600(?) thats about $35 K which leaves quite a lot for gas, food, clothes, ect on a $80K income minus 9%...
What about medical?
