I have a 2006 TSX that I bought with 92,000 miles and it is still running strong at 145,000 miles. The only repairs I have made on the car were the alternator, passenger door lock actuator, idler pulley & seized rear brake caliper. It drives nice, accelerates decently for a 4-cylinder and has almost no rattles or squeaks for it's age and mileage. I would definitely recommend this vehicle as a used car if you can find someone who maintained it well. The original Michelin MXM4 tires are worth the extra cash as they match perfectly with the car's handling abilities (wet or dry). I wish the HID headlights were made of glass as the plastic fades into a ugly haze. The leather seats are in perfect condition and the interior hardware has held up nicely. The Bluetooth phone feature doesn't work as well as newer cars and I have difficulty consistently connecting to my phone. Other than that it's a fantastic car and I really love everything about it.
2006 Acura TSX 4dr Sedan w/Navigation System (2.4L 4cyl 6M)
This car has so many pluses - handles great, bullet proof engine/transmission, a 6 speed manual shifter that is a gem. Short throw shifts - get it in the max torque band of 4000 RPM and it won't disappoint! Don't get me wrong, it's not a turbo-charged or straight 6 - 3 series, but it is priced accordingly, so please stop with the comparisons. Absolutely nothing has failed on it - the only things that have been done so far are brakes, tires, and oil changes (try that on your BMW). Do yourself a favor and install a high flow air filter, as it does make a noticeable difference. I have found the mileage to be on the high side, with no problem getting over 30 mpg on highway trips doing 70-75. Controls are very simple, but navigation is poor by yesterday's standards.
I bought my 2006 TSX with 92,000 miles in 2013 and I now have 140,000 on the odometer. I have only replaced the alternator and one door lock actuator during this time. I put a new battery, tires and new brakes/rotors on it. It would be an excellent used car for someone who is looking for reliability, sportiness, safety and comfort. At 140,000 it has no rattles or squeaks, the interior hardware has held up nicely. The leather seats are in almost perfect condition. The paint has held up even though it is parked outside in the Texas sun. The struts are original and the starter is original.
This car was purchased second hand with approximately 15,000 miles near model year end. It has provided dependable transportation around towns and on the highway and has had no major issues other than replacing the battery. I would highly recommend this vehicle to anyone!
