timing belt on 1996 Toyota Tercel

Drove Toyota after car sat approx. 2 mos. in driveway. A little sluggish, backfired than ran ok. Check engine light came on, took to my mechanic. I Asked for quote on tune up and replacing timing belt. (never replaced as far as I can tell) $596.00 for tune up (includes one ignition coil) and $647.00 for timing belt. Seems high to me. Am I wrong?

The timing belt job shouldn't be much more than $400. The tune up I don't know because I don't know the price of the coil but $596 seems way out of line.
