Maintenance and repair expence during 7 years and 143000 miles has been very low. A new transmision at 93,000 mi. was replaced by Acura at no cost. They even provided a new TL to drive while mine was in the shop. My total expense for maintenance(incl oil changes), tires, batteries and repairs is less than $1600, including a new starter at 142000 mi. It still runs and handles like new. (I dont follow scheduled maintenance). Never tuned up, but do change oil and filter every 7500 mi. I still have the original plugs. Gets 26- 31 mi/ga; I use only regular. I think it runs better on regular. I've recently towed this car with 4 wheels on ground behind my motorhome over 6000 mi without any problems.
