That's a surprise if they're near Cambridge because the Trek dealer there was Primo and I've never seen a bike shop give women ruder, more dismissive service (but I've not seen that many examples, to be fair).
I linked to the cheapest Trek that I could find on Google
and as for Primo, I've bought a few items (lights, inner tubes, etc etc) from them and have always had excellent service. I also know of 2 people that have bought bikes from them (a Scott Foil and a Cervello), and both the guys speak very highly of Primo
my bikes are serviced by Bicycle Ambulance which is just around the corner from primo, but I would not hesitate to let Primo service them if Bicycle Ambulance is fully booked
