Find Subaru Dealers in Pawtucket, Rhode Island

I got my 06 Tribeca, limited with NAV for $26,500 last August (had 10,000 miles on it) and ever since then, this dealer runs adds every week in the paper offering similar ones for less than $25,000. Carla Subaru in Pawtucket, RI

Carla's a new dealer in Pawtucket, RI has black 5 passenger limited with puddle lights, list $33,270 advertised for $26,800, believe I can get for $26,500 if I can work out price for my trade. Other dealers still willing to sell 7 passenger limited that lists for $34,900 for $27,600. Still trying to decide if I would ever have use for the 7 passenger. Apparently, the incentives have been extended to July 5 Any comments???

Dock fees from Anchor, No Smithfield RI $95. My other option is Somerset, Somerset MA. Another dealer, Clay in Norwood, MA quoted me $28300 & said he would beat everyone by $300. However, I have had excellent service from Somerset & would just as soon buy from them. They are not too far away & have been very helpful (considering I never bought my 05 Outback from them. Purchased it from a dealer in Pawtucket, RI, Capitol who went out of business shortly after I purchased the vehicle. So much for my one year of free oil changes! Just concerned about the darn gas mileage & do I really need to, and/or will gas mileage or performance suffer if I use 91 or 89. I travel around 32,500 miles per year & probably average just about 25 mpg in Outback. That's 1300 gallons say at $290 = $3770 per year. If I average 20 mpg in Tribeca, that's 1625 gallons, say at $3.10 that's $5040. If I made to with 91 octane, say at $3.00 that's $4875 still $1000 per year additional. Is the Tribeca worth it??? If gas is $4 per gallon, that's another $1600 per year. Maybe I should get a Prius???
