tiger740,
Do not think that 35K miles means these services are not required. The timing belt is 90K miles OR 6 YEARS, whichever comes first, so it is due.
35K on the OEM clutch may give you some room if it has been driven properly, but 30-50K is average clutch life, IMO.
The speaker thing is a minor cost. I need to understand a little more about the "clutch seal" to understand what needs to be done. Clutch master cylinder (Wet under the pedal?) Slave cylinder (Wet at the trans?)
Make sure the A/C and climate control is OK, read VERY EXPENSIVE.
Timing belt service would be $1200-$1500 at the dealer. Clutch, if required, add $1500-$2000 depending on parts cost and clutch choice.
Silver is beautiful! What color interior?
FYI, my 1991 has 31K miles and I just did the timing belt/water pump/90K service. I sleep better.
HTH,
LarryB
