Still holding solid at 21 MPGs. I put a set of OE size, Cooper CS5 Grand Touring tires on it about 2 weeks ago, and got it aligned, it was chewing up the inside front tires. I hoped tires and an alignment might boost the MPGs a mile or two, but there seems to be no difference.
Based on some web research, and warnings earlier in this thread, I'm pretty sure it needs a new lighting control module. I got a new-to-me light switch from eBay, and it didn't make any difference to the flickering/dimming dash lights. All interior dash lights are affected, cluster, HVAC, and radio flickering and/or going dim at the same time. There's allegedly a recall for the module, I guess if it's still active a Ford dealer would honor it, seeing as there's no Mercury dealers anymore? Worst case Dorman makes a replacement module with good reviews for ~$80.
I need to go to the dealer to get a new key anyway, so if they can do a recall on the light control module at the same time I might not feel as bad about how they're going to stick it to me for a key programing.
I had a CEL pop on, on the way to work this morning, didn't notice any performance issues, and figured it'd be something minor. Looks like I might need a new gas cap, I'm pretty diligent about making sure the cap clicks 3+ times when closing, and I'm the only one that's put fuel in it since we got it.
I tightened the cap some more and cleared the code, maybe it's "fixed" now?
Otherwise, the car is performing as well as can be expected. The new tires really improved the ride quality, not that it was bad by most comparisons to begin with. If I could get consistent dash lights and a modern headunit in the thing, I'll be satisfied for a little while longer.
I've gotten used to the brakes now, but was really considering some braided stainless lines, a more aggressive pad, and possibly larger rotors there for the first couple of weeks. Even after getting used to them, I wouldn't mind a little more stopping performance, all the years driving those VW diesels with their stellar compression braking have spoiled me.
I won't lie, thoughts of stiffer sway bars for flatter cornering have entered my mind often too, the town we live in has gone nuts with replacing stop lights with round-a-bouts.
All in due time, dash lights, keys, radio, and maybe window tint are priority now.
