2000 Acura TL-To keep or not to keep-HELP!

So here's the story (and a lengthy post)

I have a 2000 Laguna Green TL with right at 200K...

I love the car, but, it has been a bit of a pickle... I am trying to decide if its time to let go, or spend the $2500 and fix it up and aim for 300k... The car is starting to feel tired and I am noticing little things stating to not work 100%... My Question: DO I let go??? Love the car, but knowing its had 4 Transmissions (I had a dealer who was very criminal and would not repair things right)and may need #5 is the kicker

Plus, right now, the car has a list of things that need to be looked at (per my mechanic) and don't work.. I had a PPI of sorts done and this whats noted:
EGR Ports Clogged- Per CEL Light
Bank 2 O2 Sensor Out-Per CEL Light/diagnostics
MAF Sensor Reading too low-May need to be replaced-Check after fixing 02 Sensor
D4 Light Blinking and CEL Code for Incorrect Gear Ratio- Needs further inspection
Rear Passanger Door Handle Broken
Rear Windows Inop. -Checked Master Control and Rear Switches and both seem ok, possible regulator failure on both
A/C Inoperative, Leak at Evaperator
Power Passanger Seat Inop
Drivers Seat Heater Inop
Keyfobs for car have very little range; Replaced batterys and still has similar short range
Right Rear Speaker Blown
Side Air Bag Light on; Bad Pass. Side Sensor
Rear View Mirror Bad-Stuck on Dim

Thats the list... Its parked right now... I love this car, but I would have expected more life from an Acura.. I am very fastidous with maintenance on my vehicles (I had a E320 last 330K, My Current E320 has 135K and its never had an issue between me or the prior owners... I have a Saturn VUE with 165K and its fine, also have a Ford Windstar with 247K and its fine with some issues, Poor Acura)... I dunno.. Maybe I got a bad one years ago??? The prior owners bought an Expedition and I got a good deal on it, they had moved from Kentucky to NC in 03, and I have had since about that time..

So Thoughts?? Time to say good bye? Thanks
