Bertera has that reputation in CT at the Subaru store too. I would've recommended Gengras in East Hartford about 25 min farther down 91. I bought both my JTW and my wife's JLUS there.
I had a Silverado Custom before my Willys Gladiator, paid 40k out the door and traded it in and they gave 38,500 with 24k on it. they sold it for 42k a week later, more than I initially paid.
