If the timing belt would break, would it destroy the engine? I have different answers from different dealers.

The 3.0L V-6 is a free-wheeling (non-interference) engine. Toyota recommends to replace the timing belt at 90,000 miles, however in normal circumstances valve to piston damage will NOT occurs.
Here is what I have for all Toyota engines:
1.5L (1A-C, 3A-C & 3E) Interference
1.5L (3E-E & 5E-FE) Free-Wheeling
1.6L DOHC (4A-F & 4A-FE) Interference
1.6L DOHC (4A-GE & 4A-GZE) Free-Wheeling
1.6L SOHC Free-Wheeling
1.8L Diesel Interference
1.8L DOHC Gasoline Interference
2.2L Diesel Interference
2.2L Gasoline Free-Wheeling
2.4L Diesel Interference
3.0L Inline 6 (Except 1998 2JZ-GE) Free-Wheeling
3.0L Inline 6 VVT-i (1998 2JZ-GE) Interference
3.0L V6 Free-Wheeling
3.3L V6 Free-Wheeling
From this it looks like the only 3.0L 6 cyl. VVT-i (1998 2JZ-GE) is an interference engine, but it is an inline engine, not a V6.
