Choosing between the THINKCAR 391, 394 and 399 starts with your workshop's actual jobs, vehicle compatibility and ownership costs. A higher model number or a different interface does not, by itself, prove support for a particular coding or programming task.
This guide compares the packages confirmed for Programming Car Pro's U.S. store. Prices below were checked on October 4, 2026. Check the product page for current price and availability before ordering.

When to consider the THINKCAR 391
The 391 is the lowest-priced option in this three-model comparison. Start here if its supported diagnostic functions and THINKLINK Lite package meet the jobs you need to perform. Confirm coverage for your vehicles before deciding that a more expensive model is necessary.
The confirmed 391 offer includes two years of software updates and three years of connections. These are separate terms: connections are not an extension of the software-update period, and they do not include unlimited remote programming labor. Programming Car Pro's technical labor and any required OEM subscriptions or access are quoted separately.
Review the THINKCAR 391 package and current availability.
What changes with the THINKCAR 394?
The confirmed 394 package uses THINKLINK Pro, has 8 GB of memory and 256 GB of storage, and includes three years of software updates. Compare those differences with the 391's package and your expected ownership period. They do not establish compatibility with a specific vehicle operation on their own.
If you need a particular J2534 workflow, coding operation or OEM software connection, provide the vehicle and task details so the exact setup can be checked. Do not assume that a VCI name guarantees every function.
Review the THINKCAR 394 package.
What should you verify before choosing the THINKCAR 399?
The confirmed 399 package also uses THINKLINK Pro with 8 GB of memory and 256 GB of storage, but its listed price and two-year software-update term differ from the 394. The shared memory figures and VCI name are not enough to explain which model fits a specific job.
Before paying the difference, ask for confirmation of the exact functions, accessories and compatible workflow you need. Choose based on a verified requirement rather than assuming that the highest-priced scanner covers every operation.
Check the THINKCAR 399 package and discuss your requirements.
Where do the THINKCAR 191 and 195 fit?
The THINKCAR 191 is listed at $525 USD. It is a separate option to assess against your diagnostic needs; remote support is not included. Confirm the supported functions for your vehicles.
The THINKTOOL Expert 195 is listed at $1,200 USD and is a special-order option. Confirm availability and the supplied package before planning a purchase or a workshop job around it. A listed price is not a stock guarantee.
Five questions to answer before ordering
- Which vehicle makes, models and years do you service?
- Which exact operations do you need: diagnostics, active tests, coding or programming?
- Is that operation confirmed for the vehicle and the exact scanner package?
- What software updates, connections, OEM access and labor will the workflow require?
- Which accessories are supplied, and is the package currently available?
For remote work, describe the vehicle, module and operation before booking. Replacing a module does not automatically mean that programming is needed or that a scanner alone completes the job. Read about remote diagnostics and programming services; technical service is quoted separately.
