As long as you're not afraid to turn a wrench now and then, go for it. I had a Rav4 before I bought my '85 245 and hope to be a 240 driver for life. I'm even trying to talk my wife into selling her forester so she can have one too.

I never did brakes on anything and found doing brakes on the Volvo very straight forward. I've also had good luck with the Motive bleeder.

As for the brake light switch... I wouldn't change it unless your brake lights don't work.

I've been using the aftermarket junction block for about 6 months without any issues.

Very nice shirt... Just added it to my Christmas wish list.
