Good car hire experince, poor attitude at rental facility!

We arrived at the BWI car rental facility at about 10:30 PM for pickup. There were four counter reps and one customer ahead of us. It took almost ten minutes to be acknowledged as a line behind us formed. The pickup paperwork went smoothly. We were sent to the parking garage Thrifty pickup location and had to go back to the service counter to get them to locate a garage rep. We ended getting a 43,000+ mile small Jeep. The rep couldn't find the rear hatch operations in the DARK garage. Once we left to get to our destination we realized how bad the car ran and the excessive tire noise. The vehicle had very bad low speed surge/hesitation. I was in the car business for forty four years and understand cars. We rent cars 3-4 times a year, usually from Avis/Budget and never had a vehicle this bad. We had to drive this car for a week. We rented a F/S sedan to go to our granddaughters wedding. This rental was purchased because it was the FULL SIZE Chevy Malibu or similar. I shopped for this $204 rental, but the irony of all of this is AVIS emailed me a last minute AARP deal on the same vehicle @ $149 weekly total. I just stayed with Thrifty. We were told we picked a BAD day to p/u a rental by Thrifty personnel and that is how we ended up with this Jeep! VERY unprofessional!
